A common hidden fault: on panel PCB (100µF, 6.3V) goes high-ESR, causing 3.3V rail to dip during CPU boot spike. Replacing it resolves 15% of “no hardware fault found” cases.
On some Ricoh models, you can force a panel firmware reload:
Press and hold the (Red/Orange) key for about 3 seconds until the SP mode menu appears. Navigate to Reset : Select System SP . Open the Mode section (often option 5). Locate sub-menu 5810 (SC Reset) and execute the command. sc673-10 ricoh error
Power cycle
This is the most common cause, especially after a firmware update. If the Operation Panel firmware is corrupted or does not match the controller firmware version, the handshake fails. The -10 sub-code is particularly sensitive to timing issues introduced by buggy firmware. A common hidden fault: on panel PCB (100µF, 6
series) list SC673-10 as a "symptom corrected" via firmware updates. Check for the latest updates using the RICOH Firmware Update Tool or via the Application Site on your device's home screen. Basic Power Cycle : If the panel is frozen, perform a "Hard Reset": Turn off the machine and unplug the power cord for 60 seconds to clear the temporary memory. SC Reset (Service Mode)
Ricoh engineers have identified several root causes for this error. Understanding the cause is critical because replacing the wrong part wastes time and money. Navigate to Reset : Select System SP
While "Hard Disk Failure" sounds intimidating, this issue is often fixable without calling a technician, provided you are comfortable with a few basic troubleshooting steps.
